| lymphocytic leukaemia | <haematology, oncology> An acute form of childhood leukaemia characterised by the development of abnormal cellsdevelop in the bone marrow and lymphoblasts are found in blood-formingtissues. A type of chronic leukaemia found most often in the elderly, it is characterised by the presence of mature lymphocytes in the blood. Origin: Gr. Haima = blood (13 Nov 1997) |
|---|---|
| lymphocytic leukemoid reaction | Leukocytosis of varying degree, with adult lymphocytes and immature forms amounting to 40% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with pertussis, infectious mononucleosis, gonorrhoea, chickenpox, and sarcoidosis. (05 Mar 2000) |
| lymphocytic leukocytosis | A condition in which the blood contains an unusually high number of normal lymphocytes. (09 Oct 1997) |
| lymphocytic leukopenia | Reduction in the number of lymphocytes. (12 Dec 1998) |
| lymphocytic lymphoma | <oncology, tumour> A cancer of lymphatic tissues, the tumour cells are mostly abnormal lymphocytes. (13 Nov 1997) |
| lymphocytic thyroiditis | <endocrinology> Inflammation of the thyroid gland without the formation of pus. Noninfectious nonbacterial thyroid inflammation. (27 Sep 1997) |
| lymphoma, small lymphocytic | A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukaemia (cll; leukaemia, lymphocytic, chronic). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics. (12 Dec 1998) |
| aseptic meningitis | <neurology> A meningeal reaction in the cerebrospinal fluid sometimes occurring in the absence of an infecting organism. It can be due to a virus, foreign substance, diagnostic or therapeutic procedure, or to a tumour or a septic focus within the skull or spinal canal. <virology> When due to a virus, it is seen most often in those under 30 years of age. Peak time for infection is in late summer. Majority of cases are caused by the Coxsackie and echovirus. (21 Jun 1999) |
| basilar meningitis | Meningitis at the base of the brain, due usually to tuberculosis, syphilis, or any low-grade chronic granulomatous process; may result in an internal hydrocephalus. (05 Mar 2000) |
| viral meningitis | <pathology> A viral form of infection that is seen most often in those under 30 years of age. Peak time for infection is in late summer. Majority of cases are caused by the Coxsackie and echovirus. (27 Sep 1997) |
| cerebrospinal meningitis | <microbiology, neurology> Inflammation of the meninges. When it affects the dura mater, the disease is termed pachymeningitis, when the arachnoid and pia mater are involved, it is called leptomeningitis or meningitis proper. See also: aseptic meningitis. Origin: Gr. Meninx = membrane (21 Jun 1999) |

| meningitis, bacterial | Meningitis caused by species of bacteria. (12 Dec 1998) |
| meningitis, cryptococcal | A type of meningitis caused by cryptococcus neoformans. This condition is a commonly encountered opportunistic infection of aids patients. (12 Dec 1998) |
